Hi upat5-
I can't give you any advice that is "for sure" about this species. I do have a bit of more general advice of what I would try. Since this grass is native to your area, presumably it would sprout and grow there. I would try "WinterSowing" which is a technique to replicate the natural world, but a bit protected. Basically in late fall or early winter you sow the seed in a cut up one gallon milk jug then fasten the top back on, leaving the cap off. Then you leave it out in the weather, in the spring seeds sprout at the appropriate time!
Here is something else you might find helpful, it is a link to the USDA Plant Database, and amazing on-line document. At the bottom there are multiple links, one might have germination requirements for this species.
